11.1 Popular editor
LINUX has a number of text editors running in the console environment, they include:
Vim: Powerful and lightweight BSD traditional editor. VI Imacket: Heavyweight GNU Traditional Editor. RMS (Richard M. Stallman) Original. Xemacs: The next generation of Emacs is originally created by Lucid. MCEDIT: New GNU Editor. That is, the MC built-in editor. Refer to the editor, section 4.3.5. Ae: The default small editor (Potato). Never use it. NANO: Default Small GNU Editor (Woody). Similar to Pico. Joe: Used for old WordStar or TurboPascal. JED: Quick, multi-function, menu editor, compatible EMACS keyboard operation mode. JOVE: Micro Editor, compatible with EMACS keyboard operation. NVI: New VI. Bug-for-bug compatible with the Original VI.
Use the update-alternatives --config editor command to set the default editor. Many programs also use environment variables Editor or Visual to call the editor. Refer to the editor, section 4.3.5.
There are also some editors running on the X environment.
GVIM: Vim with GUI (Vim and Vim-gtk package) Emacs: The one true emacs (auto-detect x). Xemacs: Next Generation Emacs (Auto-Detect X).
These X clients command use standard options such as -fn A24, this object I have such a good guy. It is better :) See the X client, section 9.4.4.
11.2 Emergency Editor
Some editors are installed under / bin, such editors should be installed at least one to avoid editing files when / usr cannot access.
Elvis-Tiny: Minimal VI Editor (play with VI command) Nano-Tiny: Minimum non-VI editor (open with nano-tiny command) ED: Minimum editor (extremely inconvenient to use it)
11.3 Emacs and Vim
11.3.1 VIM prompt
The "Vim - Main Help File" document can be read when the program is running.
V Visual mode
i INSERT mode
: Command line command
: SET TW = 72 Set text width 72
: r! Date -r INSERT RFC-822 Data
QA records the keyboard to register a
q Stop keyboard operation record
@A Play the keyboard operation recorded in the registry A: edit foo.txt load and edit another file foo.txt
: wnext writes the current file and edit the next file
Q and @ can be used to record simple keyboard macros and then play back them. For example, if you want to create a word that macro is located at the cursor, you can enter the HTML oblique word tag, you can enter QII ^ [EA ^ [q (here ^ [means pressing the ESC button). Then, enter @i before the word, the editor will automatically add and .
It can also be found in VIM using GNUPG, section 14.4.2.

11.3.5 VIM settings
To use the full features and keywords of Vim, add the following: Add:
Set Nocompatible
Set nopaste
Set Pastetoggle =
SYN ON
Paste mode can avoid automatic indentation functional impact on the shear under the console terminal - paste operation, it is more like ": set noai".
Information about GNUPG integration is used in VIM using GNUPG, section 14.4.2.
11.3.6 CTAGS
Execute the APT-GET Install Exuberant-CTags, then you can run CTAGS in the source code file. Enter: tag function_name can jump directly to the beginning of function_name. It applies to C, C , Java, Python, and many other editing languages.
Emacs has the same CTAGS function.
11.3.7 Transforming highlight screens to HTML files
Enter SO /$VIMRUNTIME/SYNTAX/2HTML.vim in VIM command mode to convert the text on the screen to HTML code, then: w File.html,: q Exit. Special applicable to Class C is particularly applicable.
11.3.8 Separation screen with VIM
VIM can edit multiple files in a multi-split-screen environment. Want to know more about details: Help usr_08.txt.
To split the screen to display multiple different files, enter after the VI command prompt:
: split another-file
: vsplit another-file
Or after the shell prompt:
$ vi -o file1.txt file2.txt # horizontal segmentation
$ vi-file1.txt file2.txt # vertical segmentation
You can open the multi-window VI.
$ vimdiff file.txt ~ file.txt # Check the most recent modification of File.txt
$ VIMDIFF file.en.sgml file.fr.sgml # Check translation
$ gvimdiff file.txt ~ file.txt # under x
The above operations can explicitly display the difference between source files and backup files. For the SGML file, it performs label matching check, so use it to check the translation results very effective.
Specify the cursor movement with the CTRL-W command:
Ctrl-w enlargement window
Ctrl-W - Reduce Window
Ctrl-w h moves to the left side of the window
Ctrl-w j moves to the window
Ctrl-w k moves to the window
Ctrl-w l moves to the right of the window
...
The following command is used to scroll control:
: Set Scrollbind
: set NoscrollBind
